Child sex abuse inquiries explained

7 July 2014 Last updated at 19:40 BST

Home Secretary Theresa May has appointed the head of the NSPCC, Peter Wanless, to lead an investigation into the handling of documents relating to claims of a paedophile ring at Westminster in the 1980s.

She also announced a wide-ranging, Hillsborough-style inquiry into historic child sex abuse claims, "to consider whether public bodies and other non-state institutions have taken seriously their duty of care to protect children".

There are already a number of inquiries taking place into child sex abuse allegations, so how will this new wide ranging investigation of public bodies work and what impact might it have?
